Flickering after alt-tabbing ATi 4870 512MB

Hello, am I the only one to endure the impossibility to alttab from the game to desktop, as that is causing the screen to start flickering uncontrollably and nothing helps to solve that? It is not only in the actual racing, but the menu is flickering too!

I had this issues too (ati 3850) till i discovered the reason by random. The flickering only happens if you force AA and/or Adaptive-AA in the driver over the CCC or ATT.
When you select the AA modes in the game-options and turn the driver to "let the application control the AA-Settings" you are fine.

Like Andrew says. If i have multiple things to do while racing i always drive it in windows mode. Very handy for hotlapping etc You drive and you can check the site or setups while you remain in the game without having to alt-tab.

Actually, I do not know why, but the flicker in fullscreen is gone. I did a couple of changes to the driver setup of my GPU, Installed, unistalled, reinstalled and again installed Motec-Add from Alekhine, went windowed mode and back, and suddenly the flicker is gone!

I do not know what step made it happen, but I suspect booting up with "disable driver signature enforcement" and disabling ATi Catalyst A.I. prolly did the trick...

Just for the record, Im Vista 64b and running Catalysts 9.2 (i think. The help says Ver 2009.0203.2228.40314)
